The stabilisation of CORIUM

Corium is a metallic and mineral magma made up of melted elements from the core of a nuclear reactor and the minerals it can absorb on its journey.

In March 2011, during the accidents involving 4 of the 6 reactors at the Fukushima Daiichi Nuclear Power Plant, following the tsunami and earthquake of 11 March 2011 (of magnitude 9) that devastated the north-east of the island of Honshū, the cores of 3 of the 6 reactors at the plant began to melt as a result of the loss of their cooling.

On 12 May 2011, operator Tepco admitted that the fuel rods in Reactor 1 had melted down only five and a half hours after the tsunami.

In the post-Fukushima process, EDF is implementing a preventive system called “corium stabilisation”, developed by BOUYGUES CONSTRUCTION Services Nucléaires.
